alleryAmong Sc²⁺, V³⁺, Mn²⁺ and Zn²⁺, which is paramagnetic with **5** unpaired electrons?
AMn²⁺ (3d⁵)
BSc²⁺ (3d¹)
CV³⁺ (3d²)
DZn²⁺ (3d¹⁰)
Answer & Solution
Correct answer: A. Mn²⁺ (3d⁵)
**Mn²⁺ = 3d⁵** → 5 unpaired electrons, μ ≈ 5.92 BM.
Sc²⁺ = d¹ (1 unpaired), V³⁺ = d² (2 unpaired), Zn²⁺ = d¹⁰ (0 unpaired, diamagnetic).
